Onward to 5G, 6G, and Beyond
There's no denying the dramatic ways in which mobile and wireless computing have changed the world; whether in how people work, learn, play or socialize. Many can't get through a productive day without mobile connectivity, and yet, technologically, we're still at the very earliest stages of "continuous computing" or "ubiquitous connectivity" or any of the plethora of monikers used to describe our always-on, always-connected future.
From article, (5G’s main advantage is its flexibility, being able to scale up and down dynamically as needed. While that sounds obvious and much needed, it’s no small technical shakes, and experts agree that it poses something of a challenge.
“It puts a lot of stress on the RF system,” said Michael Thompson, RF Solutions Architect at Cadence Design Systems. “My team has to come up with more creative ways to control that system to make sure it’s operating in the most efficient way, whether it’s doing a little bit of voice data or massive binary data, I have to be able to adapt the RF system to make sure it’s running efficiently because no one wants their battery to run down. We want the system to operate within the specifications over very dynamic conditions and still be very efficient, inexpensive, producible, reliable, and all these things are just magnified by the needs of a 5G system.”
The flexibility in Frequency for 5G goes from 3 to 300 GHz, and it can also switch between multiplexing and access technologies CDMA and BDMA. The standards it’s compatible with include IP broadband LAN/W AN/PAN & WWWW, and its ultra high speed, with gigabit data rates, high quality coverage and multi spectrum use for near real-time performance.
In the Internet of things (IoT) or Machine to Machine (M2M) space, 5G will be able to support 100 times more connected devices, achieve deep indoor coverage and have improved signaling efficiency, all at a 90% reduction in network energy usage, which also makes it cheaper to operate.
“Of course the market expects very fast time to markets and everyone wants to be the first to get these chips,” said Moreira, adding that big companies like Samsung and Apple would be pushing their engineers hard to solve any remaining challenges. “The industry is investing a huge amount of resources into being able to solve these 5G challenges, and the chips are already coming out. In Korea engineers are working really hard to have 5G up and running in time for the Winter Olympics, so new infrastructure is already going up and companies are already testing several different techniques to make it all work.”
Meanwhile, the Middle East and North Africa is also pioneering the 5G path and are both poised to be the first to launch commercial 5G networks, according to the GSMA. In the US, Verizon recently announced it would roll out 5G service in 11 US cities by midyear 2018, AT&T said it would deliver its DirectTV Now video service over 5G to a limited number of customers in Austin, Texas, and T-Mobile intends to make 5G a high-speed pipe for VR video.
The GSMA is also predicting that by 2035, 5G will enable more than $12 trillion in global economic revenue, and support 22 million jobs worldwide.)
